Unsaturated fatty acids are essential fatty acids for the human body. According to the number of C=C double bonds, unsaturated fatty acids are divided into monounsaturated fatty acids (0-9 series) and polyunsaturated fatty acids. According to the position and function of the C=C double bond, polyunsaturated fatty acids are divided into ω-6 series and ω-3 series.
Unsaturated fatty acids have a variety of physiological functions, such as maintaining the relative fluidity of cell membranes, reducing high blood pressure, preventing vascular sclerosis, reducing high blood pressure and cholesterol. Supplementing EPA and DHA can enhance the body's immunity. At the same time, DHA is an important part of the retina, as well as an indispensable material basis for the formation, development and movement of brain cells. a-linolenic acid can improve the brain development and cranial nerve function of the fetus, and can enhance the vision of the fetus.
Too much or insufficient unsaturated fatty acids in the diet may have an impact on human health. Therefore, it is necessary to detect the content of unsaturated fatty acids. Creative Proteomics has GC-MS and LC-MS detection platforms, which can achieve efficient and accurate determination of unsaturated fatty acids.
Absolute quantification: Use external standard method to quantify, and use internal standard for correction, qualitative and quantitative is more accurate.
High sensitivity: we use liquid chromatography coupled with triple quadrupole mass spectrometers for unsaturated fatty acids analysis service (Triple Quad™ 6500 LC-MS/MS System).
